Allen&Heath GR2 PL-12 USER GUIDE 2

PL-12 Wall Plate AP6506

User Guide

The PL-12 is an ‘intelligent’ remote controller for use with the Allen & Heath GR2 audio zone mixer. It provides the non-technical operator with local control

of the music source selection and/or audio level. Up to two controllers may be connected, just one, one for each zone, or a single unit to simultaneously control both zones. A menu of setup options allows the installer to configure its function to match the specific requirements of each application. Additional switches may be wired for room combining situations and to disable the controller when the settings should not be changed. The optional PL-5 hand held infra-red remote controller adds wireless control, and additional features including the store and recall of up to 4 source/level presets. The PL-12 can be mounted into a single unit wall box using the standard face plate provided, or furniture mounted using the cutting template details given here. It interfaces with the GR2 using standard CAT5 cables. The second controller daisy chains with the first for convenient single run cabling. Space is provided on the panel for custom labelling.

aluminium wall plate is supplied according to territory, UK (part number AA5029), EU (AA5250) or US (AA5030). A suitable backing box for the UK plate can be ordered

(AA5220). The module fits into an ‘H’ shaped cutout in the centre of the face plate. The module is held using the two screws with plastic clamps provided (A). Unscrew these

from the module first. Should a custom mounting plate be required, a template (in millimetres) is provided here.

Ensure that enough space is provided for the cables.

Safety ground Ensure that the supplied aluminium face plate (or any

Connections Use standard one-to-one wired CAT5 / RJ45 cables. The

control of both zones is passed down a single CAT5 cable. Connect the GR2 ZONE REMOTE port to the first PL-12 TO GR2 port (CN1). If two remotes are used, connect the first LINK port to the second TO GR2 port (CN2). Do not connect more than two remotes. Note the maximum cable length from the diagram shown here. Use unbooted plugs to ensure the cables can fit into the backing box. Allow enough service loop for module removal.

Assigning which zone to control Set the module jumper plug to

the Z1 (zone 1) or Z2 (zone 2) position. Do this while the remote power is turned off. If two remotes are used they must not be set to control the same zone. The first remote in the chain may be set to either Z1 or Z2.

Wiring a disable switch (option) Solder pads are provide for

connecting an external switch to disable the remote and protect the settings, for example when the room should not be used. Such a switch could be located near the GR2 or in the manager’s office. Each remote can have its own disable switch. When disabled, the 4 source indicators light red.

Wiring a zone 2 follow zone 1 switch (option) Solder

pads are provided for connecting an external switch to change the operating mode so that the zone 1 remote controls both zone 1 and zone 2. This is useful when two rooms are used independently or combined into one on some occasions by opening a divider screen. When combined, the zone 1 remote controls the speakers simultaneously in both rooms. The switch must be connected to the zone 1 remote. Connect the wires to a manually operated switch or a micro-switch that changes state when the divider screen is opened or closed. When the screen is open the switch contacts should be closed. Note that setup menu option 1 may be used instead of the switch to permanently set this mode if the one remote always controls both zones. Option 8 determines whether follow affects the level and source, or source only. If source only, the level can be independently set for each zone using both remotes. If level and source, the zone 2 remote is fully disabled.

Configuring the GR2 The GR2 can be configured to operate in many

different ways. Check that its front panel DIP switches are correctly set for your application. Make sure the remote enable switches MNOP are set according to which zones you want the PL-12 units to control, and whether they should work with just the level or level and source selection. Refer to user guide AP6320. Also decide which music sources to include in the selection.

PL-12 menu options A setup menu is available to configure the

remote to match your application. For example, you may wish the source selection to scroll between 2, 3 and 4 if you have configured the GR2 for 4 music sources with music 1 a jukebox priority source that should not be selected on the wall plate. Refer to the menu table later in this guide on the options available.

Configuring the PL-12 Default setting is to select between music

sources 1, 2 and 3, to power up with the last settings, the PL-5 preset store and recall functions disabled, and the zone 2 follow zone 1 function affecting both source and level. A good starting point is to reset the remote before configuration. Refer to the reset and option menu instructions later in this guide.
